Abstract
Metal oxides are produced by forming a gas mixture containing a first metal halide, a first oxygenating gas and a fuel gas, the quantity of the latter being at least sufficient to maintain the temp. necessary for the oxidation of the metal halide, e.g. at least 600 DEG C. This mixture is burnt to produce a hot gas containing solid particles of metal oxide. This gas stream is passed into a reaction zone into which is introduced a second metal halide and a second oxygenating gas, at least one of these being introduced through a plurality of inlets, e.g. up to 20, spaced along the reaction zone in the direction of gas flow. The necessary temp. for oxidation of the second metal halide is maintained and the metal oxide produced is recovered. The first and second halide may form a white oxide and may be the same, e.g. chlorides of Ti, Al, Zr, Si. The first and second oxygenating gases may be the same, e.g. O2, or a free O2-containing gas, e.g. air or O2 enriched air. At least part of the second halide or oxygenating gas may be an unreacted excess of the first halide or oxygenating gas. The fuel gas may be CO or a hydrocarbon, e.g. C2H6, C3H8 or C4H10. The initial gas mixture may be preheated, e.g. to at least 150 DEG C., if the first metal halide is TiCl4 before being burnt. If the second metal halide is TiCl4 then the particulate metal oxide in the gas stream may have a mean size from 0.01 to 0.25 m . The ratio of first metal halide to fuel gas may be 1 : 2 to 4. The gas mixture may be burnt through a plurality of channels in a shaft furnace. The amount of metal oxide produced in the reaction zone may be from 1.01 to 10 times the total weight of metal oxide present in the gas stream. TiO2 produced preferably has a mean size of 0.15 to 0.35 m and may be formed with the addition of halides of Al, Si, Ce, Zr, and/or boron and/or water vapour and/or a subhalide of Ti and/or a source of K ions. The oxides formed from these additions may form a coating on the particles, especially if introduced after the second halide. Halogen liberated in the process may be recycled to produce further metal halide for use in the process.
